A gear in a car is used mainly in the transmission system, the steering system and the differential system. In the transmission system the gears used are helical gears these provide better efficiency, better safety and durability at high speeds, steering system uses rack and pinion type of gear system. While differential uses bevel gears. As the torque is to be transmitted perpendicularly.
Fuel generates power by being burned, oxidized is the technical term. In the process of burning, heat is released. The energy of the heat is used to do work. Exactly what kind of work depends on what kind of energy absorbing device the energy is put into. Steam power can be generated by burning the fuel under a container with water in it and using the steam for some purpose.
A differential is a particular type of simple planetary gear train that has the property that the angular velocity of its carrier is the average of the angular velocities of its sun and annular gears. This is accomplished by packaging the gear train so it has a fixed carrier train ratio R = -1, which means the gears corresponding to the sun and annular gears are the same size. This can be done by engaging the planet gears of two identical and coaxial epicyclic gear trains to form a spur gear differential. Another approach is to use bevel gears for the sun and annular gears and a bevel gear as the planet, which is known as a bevel gear differential
A pan hard rod is a bar or tube running from one side of the axle to the frame on the other side of the vehicle. It helps the leaf spring in keeping the axle centered under the body during turning a corner.
DTSI stands for Digital Twin Spark Ignition. This is used to get better combustion in the combustion chamber. In this technique double spark plugs are used to obtain better combustion of fuel in cylinder head. Through this technique fuel is ignited properly. Moreover it provides better efficiency and it is economical in fuel consumption.
The main cause of white smoke is water or anti-freeze entering the cylinder, so the engine starts to burn it with the fuel. That white smoke is nothing but steam. Prevention measures: There are special gaskets i.e. head gaskets and primary gaskets that prevent the anti-freeze from entering into the cylinder area. This anti-freeze will produce a white steam which will accumulate at the tailpipe area.
Three methods of heat transfer are conduction, convection and radiation. ● Conduction: The transfer of energy by collisions between the atoms and molecules in a material. ● Convection: Transfers heat when particles move between objects or areas that differ in temperature. ● Radiation: The transfer of energy by waves.
BHP is ‘Brake Horsepower’. It reflects the powerfulness of the brakes of the vehicles. BHP stands for how much power will be required to make the engine stop working i.e. to stop the rotation of the engine. BHP = 2 times pi times torque times revolutions; all this divided by 550. π (Pi) is 3.1416 and torque is in pounds-feet, and revolutions are revs per second
In case of cars the torque is applied to the rear wheels, thus limiting accelerator due to front wheel drive due to weight transfer. This drive is bolted to the chassis of the car. Modern manufacturers therefore design rear wheel drive to have similar handling to front wheel drive wherever possible via suspension tuning.
Large tyres provide larger surface area touching the ground, thus providing the more pulling power. Basically tractors have larger rear tyres because tractors don’t have to operate at higher speeds, thus getting the same ground speed with larger tyres. Moreover gear ratios don’t have to be as high as b/c of the tyres.
